Add function to sell all common/uncommon/rare/epic items at average price of the last 10 sales

[lavish pike]

Many people have plenty of hexes that don't use and that they just want to get rid of, if a player has hundreds of hexes it will take lots of time to list everything, the idea is to add a function to sell all of the unequipped hexes by rarity with a single click, sell price should be IMHO an average of the last 10 sales, listing duration should be picked as usual

Too easily abused.

Imagine if I had a bunch of beards, so me and my buddy bought ten of them for 200 each. We could then arguably wait an hour and sell all of ours, plus the ones we bought for 200 G a piece.
